ICACHE.MISSES Parameter on Xeon-E5

ICACHE.MISSES Parameter on Xeon-E5

I am using intel xeon E5-24xx machine. When I try to read the parameter ICACHE.MISSES, most of the applications are reporting its values as 0. If I am not mistaken it is the Instruction cache misses of L1.

Please give me any idea how to check why this parameter is giving 0 value.

However, can you please explain what is -knob enable-stack-collection=true. It is giving the readings of Energy Core and Energy DRAM. Can I say that these parameters are telling the energy reading for core and dram of a particular application.
